Moisture and standing water are among the most common causes of damage to foundations and basements. A functioning drainage system carries water away from the house foundation and protects your property against moisture damage, mould and costly settling. SFM Entreprenad performs drainage of houses, house foundations and basements that keeps your property dry and secure for decades.
Signs that the house needs draining
Contact us if you notice any of the following – it often indicates that the drainage is worn out or inadequate:
- Moisture or a musty smell in the basement or split-level floor
- Damp patches, salt efflorescence or flaking paint on basement walls
- Water that collects next to the house foundation when it rains
- Cracks or settling in the foundation and façade
What is included in drainage?
- Excavation around the house foundation down to drainage level
- New moisture protection and insulation of the foundation wall
- New drainage pipe with rodding wells
- Stormwater solution and connection of downpipes
- Backfilling with draining material and restoration of the ground
What does house drainage cost?
The price of drainage is governed above all by the size of the house, the depth of the foundation, the ground conditions (soil, clay or rock) and how the ground around the house is to be restored afterwards. Because the conditions differ from property to property, we always provide a fixed quote after a site visit – then you know the total cost before we put the spade in the ground. Drainage in connection with the home may in some cases be covered by the ROT deduction (a Swedish tax deduction).

- Site visit – we assess the foundation, ground slope and water runoff.
- Fixed quote – a clear price and schedule with no hidden costs.

Frequently asked questions about drainage
What does it cost to drain a house? +
The cost of draining a house depends on the size of the house, how deep the foundation lies, the ground conditions and whether the ground around the house needs to be restored with, for example, paving or a wooden deck. We always provide a fixed quote after a site visit so that you know the total price in advance.
How do I know that the house needs re-draining? +
Common signs are moisture or a musty smell in the basement, damp patches on basement walls, salt efflorescence, flaking paint and water that collects near the foundation. Drainage normally lasts 30–50 years, so older houses with the original drainage are often in need of re-draining.
How long does drainage take? +
Draining a normal-sized house usually takes around one to two weeks depending on ground conditions, accessibility and weather. We give you a schedule in the quote.
Are warranty and moisture protection included? +
Yes. We work according to current industry regulations, provide the foundation with new moisture protection and a drainage pipe, and give a warranty on completed work.
